It is true that the null space of a is the solution set of the equation ax = 0.

<h3>What is the proof?</h3>

The null space of a matrix A is Nul(A)= {x : Ax=0}. In other words, if A is m × n, then its null space consists of those vectors x ∈ Rn which solve the homogeneous equation Ax= 0.

Solving Ax=0 yields an explicit description of Nul(A).

Therefore, the Option A is correct.

Consider the following least squares specification between test scores and the student - teacher ratio: TestScore = 557.8 + 36.4

GenaCL600 [577]

Answer:

$Test score_i= 557.8 +36.42 Income$

If we increase the income by 1% that means that the new income would be 1.01 the before one and if we replace this we got:

$Test score_f = 557.8 + (36.42* 1.01 Income)= 557.8 +36.7842 Income$

And the net increase can be founded like this:

$Test score_f -Tet score_i = 557.8 +36.7842 Income- [557.8 +36.42 Income] = 36.7842 Income -36.42 Income = 0.3642$

So then the net increase would be:

C. 0.36 points

Step-by-step explanation:

For this case we have the following linear relationship obtained from least squares between test scores and the student-teacher ratio:

$Test score_i= 557.8 +36.42 Income$

If we increase the income by 1% that means that the new income would be 1.01 the before one and if we replace this we got:

$Test score_f = 557.8 + (36.42* 1.01 Income)= 557.8 +36.7842 Income$

And the net increase can be founded like this:

$Test score_f -Tet score_i = 557.8 +36.7842 Income- [557.8 +36.42 Income] = 36.7842 Income -36.42 Income = 0.3642$

So then the net increase would be:

C. 0.36 points

How many quarter, a pound burgers can Kristina make out<br> of 75 pounds of ground beef?<br> 1

antoniya [11.8K]

Answer:

1 quarter pound = 0.25 of a pound.

Give that:

Total amount of ground beef = pound

From 3.5 pound of beef we have to make burgers using 0.25 pound of beef in one burger

We have to find how many burgers can be made:

We have to divide 3.5 pound by 0.25 pound

i.e,

⇒14 quarter pounds burger can be made.

Therefore, 14 quarter pound burgers can George make out of 3 1/2 pounds of ground beef
